In an interview with The Business News Network on March 5, 2013 (a transcript of which is set forth below), John A. McCluskey, President and Chief Executive Officer of Alamos Gold Inc. (“Alamos”), stated that as of noon on March 5, 2013, approximately 30% of the Aurizon Mines Ltd. (“Aurizon”) shares had been tendered to the Alamos offer to purchase all of the outstanding common shares of Aurizon (the “Alamos Offer”). The percentage referred to by Mr. McCluskey included the approximately 16.1% of Aurizon shares owned by Alamos. As of noon on March 5, 2013, approximately 22.9 million shares of Aurizon had been validly tendered and not withdrawn to the Alamos Offer, representing approximately 13% of the issued and outstanding Aurizon shares, which, together with the Aurizon shares held by Alamos, represented approximately 29% of the issued and outstanding Aurizon shares. Any Aurizon shares tendered to the Alamos Offer to date remain subject to withdrawal rights.

ALAMOS GOLD INC.

TONY KELLER (BNN-TV): Well, Alamos Gold says it will extend its offer to purchase Aurizon Mines for $780 million dollars but it will not out bid Hecla Mining. BNN’s Paul Bagnell spoke with John McCluskey. He’s the president and CEO of Alamos Gold. They spoke yesterday at the PDAC Conference.

PAUL BAGNELL: I am with the Chief Executive Officer of Alamos, John McCluskey. Alamos has waived the minimum tender condition on its offer. It has also extended the offer to 5:00 pm Toronto time on March 19, 2013. Alamos, of course, in a battle with Hecla Mining to purchase and ultimately control Aurizon Mines. Aurizon is the is the owner of the Casa Berardi gold mine in Quebec. John McCluskey, thank you for joining us this afternoon on BNN.

JOHN MCCLUSKEY: My pleasure to be here, thank you.

PAUL: Tell us exactly what you’ve done today with the bid and why the financial terms of the bid have not changed, it’s the minimum tender condition and the deadline which have changed—why?

JOHN MCCLUSKEY: We changed the deadline in order to allow shareholders to tender to our bid. As of noon today, approximately 30% of the outstanding shares of Aurizon had tendered to our offer. As most people who have been following this know, if we were to take up 33% or 33 1/3 % of the Aurizon shares that would be a sufficient position to block the plan of arrangement that is scheduled for next May from going through. There would be no way, mathematically, for Hecla and Aurizon to affect a plan of arrangement merger. And so, we extended our offer in order to take up the maximum number of shares that we can in order to block that arrangement from going through.

PAUL: So, let’s quickly go through the math here—Alamos currently owns 16.1% of Aurizon Mines, correct?

JOHN MCCLUSKEY: Correct.

PAUL: 29 1/2% have been tendered to…to your offer as of today at noon is it?

JOHN MCCLUSKEY: Correct.

PAUL: And you need a further how much to block that plan of arrangement involving Hecla to go through?

JOHN MCCLUSKEY: As I said, mathematically it’s 33 1/3, but that assumes 100% of all the outstanding Aurizon shares are actually voted. This would rarely happen, especially with a listing like Aurizon which has been around for more than 25 years. Typically a listing of that age might see something in the range of 80 or 85% of the shares voted. So effectively, owning 30% is a sufficient position to block the share—the vote for going through in that …in that situation.

PAUL: Alamos has not changed the financial terms of the deal. This is a deal worth about $780 million of that about 305 is comprised of cash the rest in shares. Why not bump up the value of this offer?

JOHN MCCLUSKEY: Because we … feel quite rightly that the company was fully valued at our bid and as you noticed no other gold company stepped forward to best our offer and in fact the company that stepped forward, a silver company, was only able to do so by securing a $500 million loan against the very asset that it’s acquiring. And in doing so is encumbering that asset with a $450 million hedge position which essentially kneecaps that … that mine for the next three years. So, you know, realistically, the best offer before the investment community today is the Alamos offer and it’s based on a company with a strong balance sheet with the cash to put forward. You know, we have the $305 million in cash in place ready to give to Aurizon shareholders and, you know, that’s the way it ought to be done. We shouldn’t be trying to create companies that are candidacies for bankruptcy.

PAUL: Thank you for joining us today.

JOHN MCCLUSKEY: Thank you.

PAUL: That was John McCluskey he’s Chief Executive Officer of Alamos Gold, as the company drives toward an acquisition of Aurizon Mines.
